As I said before a continuity check of the RG 59 was good. But now I'm wondering if that simple of a test tells all. Anybody know if there is some type of load test which can be done for 100% verification?
One thing I know for sure is that when RG 59 is removed I then get a signal and every thing is fine.
No. Both cables are the same basic characteristics for the type of RV installation any of us would be dealing with except if you were running a long run from your RV to a remote satellite dish, then you would want to run the RG-6 because of its low-loss characteristics. If I were troubleshooting your problem, I would first check each connection to make sure the connectors were not either "shorted" or "open" from improper installation of the coax/cable connectors. If all that checks out and a quick check of each run with a volt/ohm meter shows proper continuity, then I would think that one of the runs within the RV was compromise either prior to or during the building of the RV causing either a direct short or more-likely a near-short that really cannot be measured except that with such a weak signal that the new Digital signals have, it saps most of it a way so that your receiver (HDTV) cannot present a picture or a non-pixellated picture. Solution, just run (if able) new coax between your outside cable coax fixture to the inside switch (just uncouple or cut the old coax out and leave in place if it is fastened down or caught in the bundle of wiring) and make sure too, any cable running from the switch to the other end of the RV for the 2nd TV connection isn't the problem too because if it is shorted, it would be the cause of your problem. We had an issue on our new `07 FunFinder in the RG-59 coax when we bought it new, luckily, this was right up my alley for fixing and I had new RG-59 to replace it. Again, mixing the same impedence coax (75 ohm) will not effect your expected reception in short (less than 50') runs for our purposes but also, if you are doing the replacement, go ahead and use the better RG-6 because it isn't that much more expensive, but you will need the appropriate coax connectors because they are slightly larger to accept the thicker inner-insulation. I hope I have helped you and not confused you or anyone reading this.
